A rigourous performance analysis of the double autpt indoction generator system with two controlled convaters hs been carried out including the effects of both the rotor side amvukr’s commutation an& and harmonics as well as the supply side converter’s harmonics. This is achieved by means of the hybrid induction machine model which allows for the changing states of conduction of the rotor side converter’s thyristors. The variations in overlapping angle of the rotor side convertex is obtained for a wide range of shaft speeds and for various firing delay angles.
